Tudor Northflag GMT (M9140G1A0U-0001)

Tudor brings back the North Flag as a 40mm flyer GMT with a Master Chronometer movement, integrated bracelet and boutique-only sales, around €5,100.

Tudor revived the North Flag on 1st September 2026 at Geneva Watch Days, five years after killing it off. The name lost its space and became Northflag, the power reserve indicator became a GMT, and the movement picked up METAS Master Chronometer certification. Everything else that made the 2015 original divisive stayed: 40mm steel, fixed bezel, integrated bracelet, black dial with yellow accents.

Background

The story starts with the 1973 Ranger II, ref. 9111/0, which gave the Northflag its integrated bracelet, its big Arabic 12 and 6, and its hand shapes. Tudor first mined that reference in 2015 with the North Flag ref. 91210N, a watch that mattered more than it sold. It carried the MT5621, the first movement Tudor developed and made itself, and the first sapphire display back the brand had ever fitted. The name pointed at the British North Greenland Expedition of 1952 to 1954, where Tudor Oyster Princes were tested in the field.

It was discontinued in 2021. Opinion softened after it left, which is the usual pattern for an awkward watch that turns out to have been early rather than wrong.

Losing the power reserve indicator is the right trade. That subdial always sat awkwardly against the 9 o'clock marker, and the dial now reads cleanly: three hands for local time, one yellow arrow for home time, date at 3.

The flyer GMT matters more than the spec sheet suggests. The local hour hand jumps in one-hour steps while the 24-hour hand and the minutes keep running, so you reset to a new time zone by pulling the crown once and clicking. A caller GMT makes you move the 24-hour hand instead, which is fine for tracking an office and wrong for actually travelling.

Pros and cons

Good

  • Flyer GMT and Master Chronometer certification at €5,100 is honest value. The nearest Rolex sits at roughly double.
  • 12.7mm thick over a 48.8mm lug to lug is a genuinely wearable set of numbers on a 17 to 18cm wrist.
  • Ceramic monobloc lume markers, not painted or applied blocks. They hold their brightness and will not yellow.
  • Display back on a €5k steel sports watch, with a movement finished well enough to justify it.
  • T-fit clasp. Eight millimetres of tool-free adjustment covers the swelling that a warm day or a flight causes.

Bad

  • 12mm lug width and an integrated attachment. You are on the Tudor bracelet for life. No NATO, no leather, no rubber unless Tudor makes it.
  • Boutique exclusive, so no dealer discount and a harder buy outside big cities.
  • 100m water resistance and a fixed bezel. It presents as an expedition watch but it is a GADA watch with a GMT.
  • The yellow will divide people. It is a straight quote from 2015, and it is the whole personality of the dial.

Who it is for

One watch, worn every day, across time zones, on a bracelet. That is the brief. It is not a field watch and not a pilot's watch, so it sits outside my usual ground: no rotating bezel, no baton-and-triangle flieger layout, no strap options. What it does have is the tool-watch legibility of a Ranger with a complication I would actually use.

Compare it against Sinn 856 S UTC if you want the same function in a more austere German package, Rolex Explorer 40 if the budget stretches and you want the safer resale, or IWC Ingenieur Automatic 40 if the integrated bracelet is the point and the GMT is not.

Alternative What you get instead Price band

Boutique exclusivity is the practical problem. It means no negotiation, and it means seeing one in the metal takes a trip. Given the yellow and the integrated bracelet, this is a watch to try before buying.

My take

Tudor fixed the 2015 watch by removing something rather than adding. The dial finally balances, the case lost 0.7mm, and the GMT is the complication the original always deserved. At €5,100 with METAS certification and a five-year guarantee, the value case is straightforward.

The 12mm integrated lug is what would stop me. I rotate straps constantly, and a watch that refuses to change clothes has to be very good at being one thing. This one probably is. Worth handling at a boutique before deciding.
